A Platform Operator is expected to restore its trading and custody services (including fully activating its contingency plan where necessary) as soon as possible and, in any case, no later than 12 hours after the occurrence of the failure. If the Platform Operator provides service to retail clients directly or indirectly (eg, through other licensed corporations), the restoration time should be shorter.

In addition, there should be proper data backup to ensure that the Platform Operator has an accurate record of client virtual assets held for each client. Transaction and client virtual asset data (eg, snapshots of critical databases) should be readily accessible to recover the production system to its latest state. As such, in addition to the daily offline backup, there should be instantaneous backup of transaction and client virtual asset data as soon as they are generated (eg, through the adoption of real-time data mirroring technology) to ensure prompt data recovery when necessary.
